What causes aging of the skin and facial features?
Several factors contribute to skin and facial aging, including changes both inside and outside the body.
- Sun exposure: Up to 90 percent of visible skin changes are caused by sun damage (photoaging).
- Smoking: Chemicals in cigarette smoke weaken collagen and elastin, speeding up skin aging.
- Air pollution: Pollutants form harmful molecules that break down collagen and elastin over time.
- Genetics: Studies of twins show that genes play a big role in how the skin ages. Some people are more likely to age earlier or later than others.
- Hormonal changes: Shifts in hormone levels, especially during menopause, can lead to thinner skin and collagen loss.
- Bone density loss: Bone loss in the face, especially around the eyes and cheeks, can cause sagging, wrinkles, and facial asymmetry.
